Four teaching techniques were used to enhance conceptual learning and to increase student performance in a course in physical-chemical principles at the School of Pharmacy of the University of Missouri-Kansas City. One of the techniques, "concept overview," is described. (MLW)

Describes a simple way of obtaining a set of relative intensities of spin-spin splitting lines using Pascal's triangle rather than calculating binomial coefficients. Provides tables showing Pascal's triangle and the relative intensities of multiplets for a range of nuclear spins. (TW)

Provided is a review of a chemical software package. The package makes possible an instructional technique that is not effective by any other means, namely the ability to view molecular shapes in three dimensions. The program can be used with either IBM or Apple hardware. (RH)

Discusses the factors affecting the behavior of a spectral function. Lists some important properties of Fourier transform (FT) pairs that are helpful when using the FT. Notes that these properties of the mathematical formulation have identical counterparts in the physical behavior of FT systems. (TW)

Reports on a study into how the history of chemistry is being taught in colleges and universities. Results indicate that courses on the history of chemistry are hardly ever required of chemistry majors, and they are offered in only 10 percent of American Chemical Society approved chemistry departments. (TW)

Describes the kinetic mechanisms of reversible activators of enzymes that normally follow Michaelis-Menten kinetics. Examines reversible activators of the enzyme carboxypeptidase A (CPA). (TW)

Discusses: (l) molybdoenzymes (examining their distribution and metabolic role, composition and redox strategy, cofactors, substrate reactions, and mechanistic possibilities); (2) structural information on molybdenum (Mo) centers; (3) modeling studies (Mo-co models, nitrogenase models, and the MO-S duo); and (4) the copper-molybdenum antagonism.…

Technetium radiopharmaceuticals are diagnostic imaging agents used in the field of nuclear medicine to visualize tissues, anatomical structures, and metabolic disorders. Bioavailability of technetium complexes, thyroid imaging, brain imaging, kidney imaging, imaging liver function, bone imaging, and heart imaging are the major areas discussed. (JN)

Discusses studies done in modeling the copper centers in the proteins hemocyanin (a dioxygen carrier), tyrosinase, and dopamine beta-hydroxylase. Copper proteins, model approach in copper bioinorganic chemistry, characterization of reversible oxygen carriers and dioxygen-metal complexes, a copper mono-oxygenase model reaction, and other topics are…

Discusses superoxide dismutase (SOD) research and the properties of copper, zinc (Cu, Zn)-SOD. Emphasizes the controversy concerning the role of Cu,Zn-SOD and other SOD enzymes as protective agents in reactions involving dioxygen metabolism, and the properties of Cu, Zn-SOD that make it an interesting biological ligand for physical studies of…

Discusses the history and function of the West-German Gesellschaft Deutscher Chemiker and its role in the communication and reward system of its discipline. Explores its role in the West German science system, exploring ideology and politics. (JM)

Describes the philosophical orientation and methodology employed in a laboratory chemistry program at Princeton University. Discusses the program's approach and use of challenging experiments, teaching assistants, and mastery teaching. (ML)

Describes (1) interfacing the Commodore VIC-20 using joystick game ports; (2) a chromatographic integrator for the TRS-80; (3) upgrading input/output capabilities of the TRS-80 color microcomputer; (4) IBM PC interfaced to a Perkin-Elmer DSC-1 differential scanning calorimeter; and (5) an undergraduate experiment in which students design a…

Describes a qualitative analysis laboratory in which students examine specific precipitates that can be used to identify copper, cobalt, nickel, and iron cations. The objective of the laboratory is to determine which test or sequence of tests unambiguously identifies each cation and to use the results to identify several unknowns. (JN)

Describes an advertising campaign designed to create awareness of cooperative education in students, parents, and business people who can sponsor co-op jobs. Discusses benefits to students, employers, and society. (JM)
